We don' t ever do repairs on appliances. And guidelines say replace, don't repair 10 yr old appliances. But a new unit looked around $1,000.What could we do?

I found screw holes on a metal strip across the top edge of the oven door. Searched the internet for someone with parts. I selected PartSelect because you have every replacement part for my 10 yr unit. Found the plastic oven door vent, range top knobs to match my unit and oven shelves. I ordered ( My husband Paul opened the oven door at the angle shown in user guide. He lifted out the oven door, then placed the door on kitchen counter. Paul took out 4 screws on the oven door top edge with a Phillips head screwdriver. He took out obvious screws, removed stove door handle, then was able to remove the yellowed plastic oven vent.
